Class MollomSpamProtector -> Fatal error

i am trying to run mollom and spamprotection (->userforms). i did all the steps in the documentation. after doing dev/build everything seems nice an clear. when i am trying to add the Field in the CMS: SpamProtection Field i get in the frontend this error:

Fatal error: Class MollomSpamProtector contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (SpamProtector::getFieldName) in /www/htdocs/w00c6fac/cms-holzmanufaktur/mollom/code/MollomSpamProtector.php on line 54

i am not shure what this mean. i looked up to the line 54 and discovered just an closing } maybe the problem is somewhere within the code?
but what is missing? and how can i fix it?

Yep just to confirm - Mollom is being updated to work with 2.4. To use it on 2.3 please lock to a revision or use a branch/tag that has been created for it.

We'll be releasing a sweeping list of module updates for 2.4 compatibility soon. If there is no release (branch or tag) which works on 2.3 please get in touch with the module developers and they can organize to maintain a 2.3 only branch if thats appropriate. With Mollom I can't think too much of the APIs in 2.4 which would break it.

Hi,
thank you for your help and your suggestions. by the way i solved my problem with recaptcha and Silverstrive-v.2.3.5.
i need to degrate my installation from 2.3.7 to 2.3.5. that was really disappointing me.
if somebody else has these problem be sure that you are using the version wich ist required.
all modules need to fit in! these combination of modules is very sensitive to run!
